Making lights and emissive surfaces work

[njord]

Hello guys.

We normally render our scene with framework functions. But for our mirrors, due to performance problems, we get the render with renderworld() function. Ofcourse by creating an extra buffer and using renderlights() function, we can render light sources too. But how to render emissive/glossive surfaces in addition ?

 

Basically I want this : use renderworld(), render light sources, see traffic light working all together.

 

Traffic light model is in LESDK 2.5\Models\Props\Switch.

It uses a switch.frag to make the lights glow in darkness by using mesh color as a parameter to shader, on line 183 :

 

gl_FragData[3] = texture2D(texture2,texcoord)*fragcolor.x + texture2D(texture3,texcoord)*(1.0-fragcolor.x);

 

Thanks in advance

Basically, when our application is like this :

 

RegisterAbstractPath("./xxx");
Graphics(800,600,0);
TFramework framework = CreateFramework();
TLayer layer = GetFrameworkLayer(0);
TCamera defaultCam = GetLayerCamera(layer);
BP L = GetLuaState();
lua_pushobject(L,framework);
lua_setglobal(L,"fw");
lua_pop(L,1);
SetGodRays(1);
SetHDR(1);
SetSSAO(1);
SetBloom(1);
SetAntialias(1);
SetShadowQuality(1);
SetTextureQuality(1);
OcclusionCulling(1);

TEntity ent = LoadModel(std::string("abstract::switch.gmf").c_str());

While(true)
{
 UpdateFramework();
 RenderFramework();
}

 

the switch.gmf emissive/glossive greenlight is lit by default. When the RenderFramework(); is changed to RenderWorld(); I cannot see any emissive greenlight. You can see the difference in the below screenshot. The traffic light on the left is rendered with RenderWorld() command, the one on the right is rendered with RenderFramework() command.

 

What I am asking is, what is the minimum code required to make emissive surfaces work, using RenderWorld(); . Afterall, RenderFramework() uses RenderWorld(), RenderLights() etc. on the background right ?

 

Thanks all

 

PS : We are insisting on using RenderWorld for our mirrors, because the performance drops immensely otherwise. However we need to see emissive surfaces such as vehicle signals and traffic lights from our mirrors. Also we need to see light sources, which can be implemented easily by using RenderLights & RenderWorld.

anyone ? tell me if i am not clear enough mates, thnx. by the way, we can try to help with mirror implementation if anyone needs mirrors in LE.
